A Study on Structural Strength in Carbody Structure of an Express Train

Abstract:

In this paper, we describe a carbody structural analysis and the result of its stress test. The purpose of this study is to evaluate the safety and functionality of the body structure operating under maximum load. The body structure was made of aluminum alloy and consisted of the side frame, under frame, roof frame, and end frame. Of these components, the side frame and under frame were the most important components in consideration of the vehicle and passenger loads. Both the structural analysis and stress test were performed under the condition that was based on the "Performance Test Standard for Electrical Multiple Units." The test results showed that the body structure is safe and stable under the condition of the designed load.
